To all whom to may concern: Belt known that I, THOMAs DOUGHERTY, i

ailcitizen of the United, States, residing at lylmneapohs, 111 the county of Hennepin and i btate of Minnesota, have invented-certain new and useful Improvements in Grain-Bins; l

and I do herebydeclare the following to be a 1 blocks.

ventilated, strong, and easily and quickly features .of construction constructed building.

The invention consists particularly in the of the walls of the building and in such other features of con 'struction and the combinations of the vafilling-door in the floor of said bridge. Fig.

, larged 7 is a detail perspective view of lar view of one ofthe blocks of 5c,

Referring more particularly .to the drawings, in carrying out my i nvention I construct the floor, walls, and roof of blocks or tile made of composition, preferably fireroof, or any suitable material.

view of one of the tile are supportedv by metal beams, and the walls arestrengthened by metatband's, as

the bin slopes from thejsides to the center, where an opening 2 is arranged leading to a chute 3, extending downward tothe horizontal passage 4, inflwhich is mounted the .endless belt carrier 5, arranged below-said blocks is preferably beveled, as at 9, from the outer face to the upper ledge 10. The central and main bearing-surface 1 1,011 the top of the foundation-block for the next row of blocks is stepped down from the ledge 10, and

atthe inner edge said foundation-block is stepped'downward again, forming the inner ledge 12, u on which the innerair-draft wall resentlyescribed is suported. A small ugojrv projection 13 exten s' from the outer ledge'and'on a of the inner face of saidledge, and a similarly-' shaped "rejection or eaterr 'ngth than the firstamentioned one, extends-fromthe level of-the central bearing ortion part way over the inner fiange. The lock=is rovide'd-with'an air-passage 15, extending' l bmthe central portion of the inner ledge at thefbase of the lug inwa ,dly at a The roof-- to receive the wedge-shaped tongues '7,v

The .fioo'r 1 of broadfoundationgether; The upperouter edge of each of said level therewith at the center slightobli ue and opening upon the inner face of sai block. The'nextrow of blocks 16, arranged above the foundation-blocks, are not as thick .as .said feiindation blo'ck, but

' 5 only-extend from within the outer ledge to 1- *the' innerfac'e of the lugs 14 on the lower f ledge of said-latter blocks. Eachof said blocks lfi has-a lateral tongue 17 and groove 218, as inthe feundation-blocks; but they are |o preferably arranged on the oppositeedges+ .;tlhat-is, if the tongues are on the left-hand sidefof thefoundation-blocks the tongues on the blocks l fi will be on the right-hand side,

as shown clearly in Fig. 3. Said blocks 16 1'15. each have a central inner and downwardlyextending lug I9, adapted to fit between the adjacent ends of the lugs L4 on the inner ffiange of the foundation-blocks. The rear lower-edge of said block 16 is cut out at each 20 end, as "at "20, to'fit overhalf of the outer lugs l,3.- onfthe foundation-blocks, and a lug 20 'projeets-iipward at the center of the upper flbutel edge" of said block'16. It'will thus be.

seen that the blocks 16 are arranged over the .tongue-and -grooire joints of the foundation- -'jhlocksg andlthat their-' sirnilar j oints-are arranged ver. the center of said foundationblock '0 wardly projecting outer lugson the blocks of the successive rows above the foundation interlock with the spaces left therefor in the other blocks and brace the wall and-render it capable'Ofiwithstanding "gqzeatpressure fromv adapted for grain-bins. V

' 1 As shown in'Fig. 3," the first row "of: the blocks 16 have curved grooves 21 in their-upper surfacest'o receive a metal hoop-or brace- 3 5 within,*making the construction particularly 4o bar'22; l/V hil'e ,"thisarrangement of'groove and hoop is only shown in the first row of blocks above the foundation,.it.inay be re'-- eated'in as many of the rows above as may- I be desired. It isfpreferable' to. arrange said.

4 5 hoops orbrace bars at intervalsup the wall',. say about three in a wallof ordinary height. Asa-shown in-Fi'g, 7, the. blocks'1-6. and

those ofthe {successive supper rows may be made "in skeleton form'- and 1 provided with 50 vertical'openings or cavities 23 in the center thereof. These openings make the blocks lighterto handle anddo not appreciably decrease their strength. The upper rows of'- wall-blocks are made in the same'way -as' the 55 blocks 16 just described, and the; tongues of 1 eachsuccessive row are arranged on the opposite sides of the blocks from which they *areplaoedi on theinext lower row. The'top rowof. said blocks is provided with [a ledge".

'- "6o-24 ,;-u'pon which-rests theleorniee tile or blocks 2'5l .Each of said cornice-hlocks has: an inwardly-extending portion'26, prov ded Withputput, oi-dons or sockets at each endto fit over ha ofth'e upper lugs of the top [65 1 rowiof wallebloclis below it. -Said corniceivillalso'be noted that the down-i -I wardly" -projecting inner lugs a'ndfthe upaaaes a blocks are'provided witha molding 27, projecting over the edge of the'wall; and it may have an ornamental edging, as shown, to add to the, appearance of the structure Said molding extends 'down' below the other portions ,of said cornice-blocks, leaving aspace between it and the outer surface of the main wall to receivethe upper edge -of the upper row of the outer wall tile or blocks'presently described The cornice-blockshave flateral tongue and groove connection with: each other, as in the other blocks. l

The outer wall, whieh rests upon theouter flange of the foundationeblocks, is built-of blocks 28, made, preferably, Of the sani'e ma- 8 terial as the main-wall blocks, but much narrower,- being just wide enough to cover the outer flange of the .foundation-bloeks 'at the base and fit between the outer surface of the main wall and the molding of the cornice. Said outer-wall blocks are preferably pro vided with vertical -0 'enings, as shown", for lightness and ventilation and are secured by lateral tongue-and-groo'ye joints in rows. Each successive row of these blocks above the first is-provided' with an outerflange' 29, adapted to fit upon an outer flange on the row below, thus locking the'latter in against the main wall, the top row of the blocks 23 of the outer wall extending within the downwardly extending ortion ofv the molding' of the cornice and ho ds all below'itin place. The inner air-draft"wall 31 is also composed of rows of grooved bljdcks-32, adapted. to be secured together by ,we'dge-shap'edl' tongues, like thoseused for the niain wall blocks, and arranged one above the other, the "bottom row'resting upon the inner fian'geof the foundation-blocks and the upper row ar-' ranged near the top of the main Wall. 3 The circular form of the inner wall, together with the 'tongue-and groove. connection [between the blocks of 'each' row,.prev'entswsaidlwall from. falling inward. Each ofthe blocks. 32 is provided with vertical air-passages 33, [which in construction arearranged to regis terWithth'ose' in the block below. Each ofthe'blocks also has an oblique passage 34 opening on its inner faceand communicating with thepassage 33 below-[the overhanging flange 34 of the block in the 'row-.ab 0ve, which ledge rests upon a ledge 35 of the block described. :The flange 34 is preferably un'- 'dercut, as at 36; oppositethe passages 34 to give a freer comniunlcation to thepassage 33. aid flan e extending down below the junc ture of t e passages34 and 33 prevents the 'grainfroin: assingintfo and sto ping the pas;-

T he uppered'ge of said blocks 38 preferably imperforate andprotion instead of having .tion extends down from the blocks of one I rbw over each separate passage in the blocks 4 therethrough, as in. the roof-blocks. These ping step' ed ends-that-' is, the larger en block is so" connected to the smaller end or.- the larger block, while the stepped portion or blocks-47 and48, respectively, Figs"16'and l7. 49' (shownin Figt) are arranged endwise'in of the row below." y

. The top row of blocks of themain wall is providedwith recesses 40 for the angle-irons 45., Whichsupport the roof-tile overlapping stepped edges 42. rounded in form, the spaces between the par;- allel angle-irons being-filled with said roof 1 tile or block 42, as shown in Figs, 13 and 14 Said blocks are provided with the ventilatingpassages 43. hown in Fig. v15.)
